Heat CapacitySpecific Heat Capacity
It is the amount of heat energy required to raise the temperature of entire body by 1 °C.It is the amount of heat energy required to raise the temperature of unit mass of the body by 1 °C.
The S.I. unit is JK-1S.I. unit is J kg-1K-1.

(ii) Heat Capacity = Mass x Specific Heat Capacity
